  supertype:  junction.connector__conjunction  something that joins or connects
  subtype:  distributor_point__distributorpoint__breaker_point__breakerpoint__point  a contact in the distributor; as the rotor turns its projecting arm contacts distributor points and current flows to the spark plugs
  subtype:  electrical_contact  contact that allows current to pass from one conductor to another
  subtype:  short_circuit__shortcircuit__short  accidental contact between two points in an electric circuit that have a potential difference
  subtype:  sound_bow__soundbow  contact (the part of a bell) against which the clapper strikes
  subtype:  terminal.contact__pole  a contact on an electrical device (such as a battery) at which electric current enters or leaves
     subtype:  anode.terminal  the negatively charged terminal of a voltaic cell or storage battery that supplies current
     subtype:  negative_pole  the terminal of a battery that is connected to the negative plate
     subtype:  positive_pole  the terminal of a battery that is connected to the positive plate
  subtype:  tread.contact  the part (as of a wheel or shoe) that makes contact with the ground
  subtype:  wiper_arm__wiperarm__wiper__contact_arm__contactarm  contact consisting of a conducting arm that rotates over a series of fixed contacts and comes to rest on an outlet
